| 2008-11-12 | freezer_cg: disable writing freezer.state of root cgroup | Li Zefan | |
| With this change, control file 'freezer.state' doesn't exist in root cgroup, making root cgroup unfreezable. I think it's reasonable to disallow freeze tasks in the root cgroup. And then we can avoid fork overhead when freezer subsystem is compiled but not used. Also make writing invalid value to freezer.state returns EINVAL rather than EIO. This is more consistent with other cgroup subsystem.

| 2008-10-20 | container freezer: document the cgroup freezer subsystem. | Matt Helsley | |
| Describe why we need the freezer subsystem and how to use it in a documentation file. Since the cgroups.txt file is focused on the subsystem-agnostic portions of cgroups make a directory and move the old cgroups.txt file at the same time.
